There are the short, clipped boys’ names that are popular in the U.S. and widely used in the Netherlands, too, with such ethnically discordant choices as Finn and Levi ranking especially high, and nickname names such as Joey, Jordy, Mike, Nick, and Rick also in vogue.

Then there are the names that are familiar but relatively rare in English-speaking lands, from Bart to Dion to Guido. Milan, Ruben, and Bram, among this group, are some of the top boys’ names in the Netherlands – certainly startling to an outsider.

And then there are the many boys’ names that are widely used in the Netherlands and virtually unknown outside that country. Daan, the #1 name, is a form of Dan, but ever heard of Sem? Gijs, Rens, or Timo?

Most popular Dutch names, whether seemingly adopted from 1950s American sitcoms or native to Holland, feel abbreviated, with an occasional diversion to the Latinate (Giovanni) and the plain old Latin (Floris and Adrianus).
